1916] Fernald, — The Genus Sabatia in New England 147 



characteristic coastal plain species as Sparganium lucid urn, Sagittaria 

 teres, Scirpus Longii, and Utricularia resupinata, lends weight to the 

 possibility that the Sabatia is also indigenous. 



Sabatia stellar is, the halophytic annual, is little known in New 

 England east of the western shores of Narragansett Bay. It is on the 

 marshes of Martha's Vineyard and locally at Dartmouth, Massachu- 

 setts. The writer has seen no material from east of Buzzard's Bay, 

 but there is a report of the plant at Amesbury and Salisbury at the 

 mouth of the Merrimac, 1 and an old record of it at York, Maine. 2 

 The latter record is unsupported by specimens though there may 

 originally have been material; but Mr. Sears's record of the plant 

 from Amesbury and Salisbury was based on a single specimen now 

 preserved in the herbarium of the Peabody Academy of Science. 

 Through the kindness of Professor A. P. Morse the writer has exam- 

 ined this plant which was found on September 22, 1885, by Mr. Eben 

 True whose communication states that he found but a single plant in 

 a hay field. The specimen is not S. stellaris but very characteristic 

 S. angularis (L.) Pursh; and its occurrence as a single individual in a 

 planted field indicates that it was only a casual adventive. In his 

 note Mr. Sears refers to S. stellaris as found at Pembroke, Massa- 

 chusetts; but the plant upon which the Pembroke record was based 

 is Mr. Foster's specimen of S. campanulata above referred to. 



Besides S. angularis, just referred to as casually adventive in Xew 

 England, the related S. campestris Nutt. has occasionally been found 

 as a casual infields and waste places, but it has not, apparently, become 

 established in Xew England. 



The other two species of New England are the larger-flowered plants 

 which generally pass as Sabatia dodecandra (L.) BSP. or S. chloroidcs 

 (Michx.) Pursh. S. dodecandra was based on Chironia dodecandra L. 

 Sp. PI. i. 190 (1753) which in turn went back to " Gentiana floribus 

 duodecim-pctalis," etc. of Gronovius, Virg. 29 (1739). The latter, 

 based upon Clayton's no. 120 from Virginia was described as having 

 the corolla-lobes "lanceolate" and Mr. S. F. Blake, who has examined 

 the specimen, reports the corolla-lobes to be only 5 mm. wide. Later, 

 in the Systema, ed. 12, 267 (1767), Linnaeus transferred his Chironia 

 dodecandra, without additional characterization, to the Old World 

 genus Chlora; and in 1803 Michaux described from New York and
